Abstract (en)

[origin: WO2006132628A1] Disclosed herein is a method of forming pigment pseudoparticles from pigment particles, comprising polarizing the pigment particles with a gas and agglomerating the polarized pigment particles to form pigment pseudoparticles. Also disclosed herein is a pigment pseudoparticle comprising pigment particles bonded together primarily by an induced level of intermolecular electrostatic attractive force, wherein the pseudoparticle is substantially free of internal dust. Furthermore, an apparatus is disclosed herein for creating pigment pseudoparticles from pigment particles, the apparatus comprising a hollow vessel having an inner cylindrical surface, a plurality of scoops extending inwardly from the inner surface and positioned along the axial length of the hollow vessel and means for passing pigment particles through the gas. Additional embodiments of the invention are disclosed herein.
